I own a Mazda Cx5 white, i would like to protect the black exterior vinyl around the tyre and the plastic trim which turn to dark gray. Could you advice me a product i can buy and apply please ? Where to buy it in Hua hin or ask to do ?

In my opinion the below is the best on the market and has been for a long time. However, I don't know if it's readily available here. Over to others more experienced about what's in the shops........ Pete
